Pledge to never use pop ups, top banners, etc.
I understand there is an opportunity to advertise on Mint, but please remember the uniqueness of this site - customers don't want to see too much advertising near their financial info. It makes Mint look cheap and discredits the brand. If I ever see a pop up or top center banner add while logged in, I'll likely pull my account and never return again. I'm sure there is enough business in selling the aggregate information. I would even pay a nominal fee if necessary. But Intuit should still be focusing on quality assurance--it was obvious to customers when Intuit bought Mint - the glitches were numerous and worrisome. You're not out of the woods yet, so this is not the time to put up ads. Do you have 100% confidence in this? You depend highly on word of mouth and trust for your customer base. Don't lose it.
